An Apple Store was tipped for Macarthur Chambers on Queen Street, but it has not arrived. A story in Brisbane Times suggests it has been delayed due to a contractor going bust.
Laing O'Rourke reports that it has signed up a two level Apple store at its McLachlan & Ann (M&A) building in the Valley. See Press Release.
The Apple Press Release website had no news last time I looked, but the Apple job website says that there will be a new store in Brisbane.
I suspect it will be a positive influence to have an Apple Store nearby.
